Why do so few people who try to deadpan a dry, sardonic retort seem to miss it when it's redirected back at them?

Calm down, it's only ones and zeros.

Japanese has undergone a number of romanizations and these romanizations have endured several revisions. The revised Hepburn system is based on English phonology and is what one will usually encounter in English; under this system 柔術 is written as jūjutsu. Nevertheless there are still relics of past systems that linger (Godzilla comes to mind, today we'd write Gojira).

I am not familiar with the history of jūjutsu's romanization but I do know that jūjitsu is not the same word as jūjutsu. Jūjitsu (充実) is defined by the WWWJDIC as being either (1) fullness; completion; perfection; substantiality; enrichment; (2) replenishment; repletion; (P).

The WWW JDic does not define what is and is not english... except to a sinophile.
